BAND-CUTTER AND FEEDER FOR TH RASHERS.

SPECIFICATION forming part of Letters Patent No 344,145, dated June 22,1886.

Application filed October I, 1885. Serial No.178,706. (No model.)

To aZZ whom, it may concern:

Be it known that I, WILLIAM TENNISON, of Mount Vernon, in the county of Posey and State of Indiana, have invented certain new and useful Improvements in Band-Gutters and Feeders for Thrashers, of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similarletters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan View of my improved band-cutter and feeder, shown as applied to thrashing-machine, parts being broken away. Fig. 2 is an elevation of the same, partly in section, through the line a" x. Fig. 1. Fig. 3 is a sectional elevation of the same,'taken through the line y 3 Fig. 2.

The invention consists in the construction and combination of various parts of the'feeder and band-cutter, as will be hereinafter fully described, and then pointed out in the claims.

The combined band-cutter and feeder can be placed at either or both sides of the feedhopper of the thrashing-machine, as may be desired. The latter arrangementis illustrated in the drawings.

A representsa portion of a frame of a th rashing-Inachiue. to the forward part of the frame of which is secured the casing B of the combined band-cutter and feeder. To a journal of the cylinder of the thrashing-machine A are attached a fast pulley, O, and a loose pulley, D, to receive a driving-belt. To a shaft, E, of the thrashing-machine is attached a crank-wheel, E, to receive a belt, F, which also passes around a pulley, G, attached to the shaft G. The shaft G revolves in bearings attached to the forward part of the casing B and is conuectedby an ordinary shaftcoupling, H, to the journal of the roller H, journaled in the forward part of the frame of the thrashingmachine, around which roller passes the lower part of the endless feed-apron I. The upper part of the endless feed-apron I passes around a roller, J, journaled to the forward end of the frame of the thrashingmachine A, so that the said endless apron will carry the grain to the cylinder of the thrashing-machine.

To the end of the shaftG is attached a bevel gear-wl1eel, K, the teeth of which mesh into the teeth of the bevel gear-wheel L, attached to the end of the shaft M. The shaft M isjournaled in bearings in the casing B and upon it are formed eight (more or less) cranks, N, projecting in different directions, and to which are pivoted the lower ends of the lower feeder-arms, O. The middle parts of the arms 0 are widened and have curved slots P formed in thein, through which passes the shaft Q, to serve as a fulcrum to the said arms. The slots P allow the arms 0 to move up and down, and the fulcrum-shaft Q, in con nection with the curvatu re of the slots P, causes the upper ends of the said arms to move upward, forward, downward, and backward as the crank shaft M N revolves. The upper ends of the arms 0 in their upward and forward movements move through slots R in the inclined feedtable S, secured in the upper part of the casing B, so that the said arms in their forward movement will feed the bundles of grain or clover seed down the said feedtable and in their rearward movement will pass beneath the said bundles. Near thelower end of the feedtable S the bundles pass beneath the lower edge of a plate, T, attached at its upper part to a shaft, U, journaled to the sides of the casing B. The lower edge of the plate T is held down near the feed-table S by a spiral spring, V, the lower end of which is attached to the said plate near its lower edge. The upper end of the spring V is attached to a cross-bar, B, of the casing B. The movement of the plate T, and consequently the rapidity of feed, is regulated and the machine is adapted to feed damp or dry grain by a set screw, IV, which passes through the crossbar B of the casing, and against the forward end of which the plate T, or a block or bar, X, attached to the said plate, strikes. As the bundles pass out from beneath the lower edge of the plate T they come in contact with and their bands are cut by the V- shaped teeth of the cutter Y, attached to the bar Z, the ends of which slide in bearings in the casing B. To the inner end ofthe bar Z is pivoted the end of a lever, a, which is pivoted at its middle part to a support, b, attached to the casing B. The other end of the lover a is pivoted to the upper end of a tached to the shaft i, which revolves in bearings in the upper part of the casing B, and

upon whichare'formed eight (more or less) cranks, j, projecting in difierent directions.

To the cranks j are pivoted the upper ends of the upper feed-arms, k, the middle parts of which are widened and have curved slots l formed in them to receive the rod m. The rod m at its, ends is attached to the casing B, is passed through the slots at of thefeedearms 7c,

and serves atulcrurn to, the said feed-armsl With this construction, asthecrank-sha-ft-t j is revolved, the lower eudsof the upper feed- -rms, k. a are. meted upwa ward, down a and inwar a dv he cr nk-shaft.- i j" and fulcrum-rod m are so arranged thatthe-lower e dsof the. said, upper feed arms, lawn-1 m ve ar lose t the cutter Y,v o a to. take. the grain as it passes, the saidcutterand feed. it evenly and regular-woven the endless feedap by hich t. i ca ried to the. thrash-- s ma hine A Thefeedi-arms k are held from lateral move-l ment by, passing through slots at ina table, 0,

The elevator r is, driven. from the crankshaft 13, as indicated in Figs. 1 and 2.

Having thus described my invention, what I 1 claim as new, and desire to, secure by Letters Patent, is-

1. The combination of the endless feed-apron I, the slotted feed-table- S, theset of vibrating arms 0, for feeding the bundles down the said feed-table, the vibrating band-cutter Y, the

set of vibrating arms k, for feeding the grain from the cutterto the said endless feed-apron, and a driving mechanism, as set forth.

2. The combination, with the slotted feedtable- S, the setot will)irating ai-ms(D, and their d rivingwmechanism,ottheswi ngi ng gage-plate ;I, the holding-spring 'V, and the regulatingscrew W, substantially as herein show-n and sdescrihed, whereby the passage of the grain ifrom the said feed-table is regulated, as set fOIth'. 1 I

3. The combination, with the endless apron I, the slotted feedtableS, and a driving mech- ;a,n-ism, of thechamber 1), the elevator-r, and

a the spent 8-, substantially as herein shown and described, whereby the kernels of grain falling through the slots of the feed-table are carried to the thrashing-machine, as set forth.
